TAMRON OBJEKTIV TEST MANUAL

It can focus down to a max object magnification of 1:2 (hence the M1:2 in the lens name). There were frequent discussions whether to prefer the Canon EF 28-135mm f/3.5-5.6 USM IS because of image stabilization or this Tamron lens due to its extra kick at the wide end of the zoom. A specialty of the lens is its close-focusing capability. The Tamron AF 24-135mm f/3.5-5.6 SP AD Aspherical (IF) was a very popular lens during the film era targeting especially travel and outdoor photography.

As usual, manual focusing works 'by-wire'. When stopped down, you can hear that the camera is opening/closing the aperture during focusing operations. The lens doesnt feature an aperture ring (a G. The same can't be said about the aperture mechanism. AF speed is ok (certainly fast enough for an ultra wide angle lens), but lacked precision in our field tests. One possible scenario: 60+ MP and 3,499 price tag. Typical for this focusing type, the AF speed is on the slow side but it's at least noiseless. A mirrorless version of the Nikon D850 meaning a slower, high-resolution camera. The AF system uses a linear extension system. One aspect that differs from the 35mm f/2.8 is the petal-shaped lens hood - which in turn is the same as the one used for the Tamron 20mm f/2.8 Di III OSD M1:2. It isn't fully clear why Tamron designed the lens to be relatively long because this tube is quite deeply recessed by about 1.5cm. The Tamron 70-300mm /4-5.6 VC USD offers good but not great CA tolerance, with some light magenta-green fringing appearing in areas of high contrast in corner areas. While the length of the lens doesn't change during focusing, there's a moving inner lens tube. Surprisingly, the lens has some seals making it moisture resistant albeit there isn't a word about dust protection. The rubberized focus ring operates smoothly but there is a cheap feel to it. With DXOMARK you can display the lenses with three different. You can also select a camera to see the results for all the lenses tested on it.

The chassis is made of average quality plastics based on a metal mount. DXOMARK's comprehensive camera lens test result database allows you to browse and select lenses for comparison based on their characteristics, brand, price, lens type, lens size, focal range and aperture. At around 250 USD/EUR, it is among the most affordable prime lenses on the market.įor this amount of money, you can't expect professional-grade build quality. And at least regarding its pricing that's a good thing. Projection lenses, test plates, high precision molds, injection-molded. Other than its optical design and name, it is basically indistinguishable from its two in-house cousins (with the third one being the 20mm f/2.8). Tamron Co., Ltd is a Japanese company manufacturing photographic lenses, optical components. But you can use MTF charts as a scale to measure lens performance.Review by Klaus Schroiff, published August 2021įollowing our review of the Tamron 35mm f/2.8 Di III OSD M1:2, let's go a little wider with the Tamron 24mm f/2.8 Di III OSD M1:2 - thus a moderate ultra-wide angle lens with typical applications such as street photography or landscapes. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. You can simulate images shot with various combinations of lenses, ranging from wide-angle to telephoto, and cameras, in different. Performance characteristics of photographic lenses cannot be expressed with only MTF charts. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.

Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. The pictures above also show there isn't much light fall off at the edges. Tamron Sp Af A001 70 200 Mm F 2 8 Ld Di If Af Sp Objektiv Gnstig. The Tamron 150-600 mm lens shows a small amount of pincushion distorsion in the middle zoom range. Tamron 28 200 Mm F2 8 5 6 Di Iii Rxd Test D Pixx is top nude porn. Lens performance differs depending upon directions. The same test with the Tamron 18-200 mm zoom lens reveals significant barrel distortion at the long end. The closer the 30 lp/mm curve (the thin line for high frequency) to '1' (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be. Ltd., vilghresen minsgi optikk vezet gyrtja bejelentette, hogy az Eurpai Kpalkot s Hangszvetsg (EISA) hrom TAMRON objektvnek. The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to '1' of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. augusztus 15.-n Saitama, Japnban a Tamron Co. MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.
